His brutal movies put Korean cinema on the map. Now the director of Oldboy is back with a blistering satire about a man driven to murder after redundancy

The Korean wave is being feted around the world right now but Park Chan-wook is not feeling too celebratory. From the outside, South Korea seems to be a well-oiled machine pumping out a stream of world-conquering pop music, cuisine, cars, cinema (especially the Oscar-winning Parasite) and TV shows, as well as the Samsung flat-screens to watch them on. But Park’s latest film, No Other Choice, bursts the balloon somewhat. It paints modern-day Korea as an unstable landscape of industrial decline, downsizing, unemployment and male fragility – with no KPop Demon Hunters coming to save the day.

“I did not mean it for it to be a realistic portrayal of Korea in 2025,” says Park, a serene, almost professorial 62-year-old. “I think it’s more accurate to view it as a satire on capitalism.”

Forecasts suggest that global heating could create a shortcut from Asia to North America, and new routes for trading, shipping – and attack

Another week, another freak weather phenomenon you’ve probably never heard of. If it’s not the “weather bomb” of extreme wind and snow that Britain is hunkering down for as I write, it’s reports in the Guardian of reindeer in the Arctic struggling with the opposite problem: unnaturally warm weather leading to more rain that freezes to create a type of snow that they can’t easily dig through with their hooves to reach food. In a habitat as harsh as the Arctic, where survival relies on fine adaptation, even small shifts in weather patterns have endlessly rippling consequences – and not just for reindeer.

For decades now, politicians have been warning of the coming climate wars – conflicts triggered by drought, flood, fire and storms forcing people on to the move, or pushing them into competition with neighbours for dwindling natural resources. For anyone who vaguely imagined this happening far from temperate Europe’s doorstep, in drought-stricken deserts or on Pacific islands sinking slowly into the sea, this week’s seemingly unhinged White House talk about taking ownership of Greenland is a blunt wake-up call. As Britain’s first sea lord, General Sir Gwyn Jenkins, has been telling anyone prepared to listen, the unfreezing of the north due to the climate crisis has triggered a ferocious contest in the defrosting Arctic for some time over resources, territory and strategically critical access to the Atlantic. To understand how that threatens northern Europe, look down at the top of a globe rather than at a map.

I love the way we are both looking in astonishment at my son. It shows the unwavering support she gave me when he was born

This picture of my mother, me and my eldest son, Theo, was taken the morning after he was born in May 2002, in University College Hospital, London.

There are a lot of things I love about it. I love the fact my mother is exquisitely dressed – she’s wearing her pearls! She always looked very elegant at this time in her life and enjoyed clothes (we bought that suit on a day out together). I love the composition too – our three dark heads, faces in profile and the way our three hands are aligned. I love the miracle of my son’s intricate little shell of an ear, the nose (his dad’s) and lips (mine) still visible now in his 23-year-old face.

Our fitness expert clocked up his indoor miles to put the best exercise bikes, including simple spin machines and gym-quality models, to the test

• The best treadmills for your home, tested

Cycling has the potential to benefit your health in myriad ways, whether it’s the mood-boosting properties of inhaling fresh air, the social element of riding with friends or the simple act of improving cardiovascular fitness with every pedal stroke.

The UK weather doesn’t always play ball, though, so for those who don’t want a dire forecast to result in a missed workout, indoor training replicates the exercise (if not the fresh air).

Cyclists and others voice frustration as transport infrastructure descends into chaos amid increasingly rare cold snap

A week-long winter cold snap that would once have been normal in the Netherlands has caused more than 2,000 flight cancellations, chaos on roads and railways, buildings to partially collapse, and a stream of angry cyclists asking why roads seem better gritted than cycle lanes.

Since Saturday, up to 15cm of snow has fallen across the country, with temperatures of -10C (14F) including wind chill, sparking angry commentary over how some nations manage months of snow but the Netherlands, no longer used to it, appears paralysed.

Road, rail and air travel disrupted across the UK as Storm Goretti brings wind, rain and snow to the UK and parts of Europe

• Tell us: how have you been affected by Storm Goretti?

Officials in the West Midlands have warned of the “worst snowfall in a decade” as parts of England and Wales prepare to be hit with 5-10cm of snow on Friday, and up to 15-25cm in some areas.

In a statement on Wednesday, Stoke-on-Trent city council reassured residents it had not run out of grit after “misinformation” began to circulate. It said:

We are now facing the worst snowfall we have faced in 10 years. The Met Office has predicted that we could have 3.5 inches of snow and temperatures as low as minus 4C on Thursday into Friday morning. As a result, we are carefully managing our resources and stock of salt.

Unfortunately, we have been made aware of some misinformation circulating regarding the council’s salt supplies and gritting operations. It simply isn’t true that we have run out of grit.

The current cold snap is now expected to last at least until this weekend according to Met Office forecasts, and we know that prolonged exposure to low temperatures can have a severe impact on people’s health, especially if they’re older or have serious health conditions.

That’s why we’re urging people to check in on friends, family and neighbours who may be more vulnerable to the cold and make sure that they’re able to keep themselves warm while this period of cold lasts.

Image-creation function has been limited to paying subscribers after Elon Musk’s platform was threatened with fines and regulatory action

In the US, Anna Paulina Luna, a Republican congresswoman, has said that, if the UK bans X, she will try to legislate to sanction not just Keir Starmer, but Britain as a whole.

In a post on social media, she said:

There are always technical bugs during the early phases of new technology, especially AI, and those issues are typically addressed quickly. X treats these matters seriously and acts promptly. Let’s be clear: this is not about technical compliance. This is a political war against @elonmusk and free speech—nothing more.

Security forces reported to have killed at least 45 people since protests began 12 days ago, as protesters gather in Tehran

Iran was plunged into a complete internet blackout on Thursday night as protests over economic conditions spread nationwide, increasing pressure on the country’s leadership.

While it was unclear what caused the internet cut, first reported by the internet freedom monitor NetBlocks, Iranian authorities have shut down the internet in response to protests in the past.
